A low-calorie tea,
with 20g of protein.
Kalo is a brewed mango & orange tea finished with grass-fed whey isolate. No added sugar, no artificial flavors.

Five things.
Nothing else.
Most ready-to-drink protein hides behind a paragraph of additives. Read the label. If you can’t pronounce something, we didn’t use it.
- 01
Brewed black tea
Whole-leaf assam, cold-brewed for 14 hours so it pulls flavor without bitterness.
- 02
Cold-pressed mango
Ataulfo mangoes — the small honey ones — pressed and pasteurized within 24 hours of harvest.
- 03
Valencia orange
Juiced with the pith on, which is where the bitter-citrus aromatics live.
- 04
Whey protein isolate
Sourced from a single dairy in Wisconsin. Cross-flow microfiltered, never heat-denatured.
- 05
Sea salt & lemon
A pinch of salt and a squeeze of lemon to round the finish. That’s the whole formula.
We made the drink we couldn’t find.
Kalo started in a small kitchen in Oakland in 2024. We’d spend mornings at the gym and afternoons at our desks, and we never found a drink that fit both. Shakes were heavy. Protein waters were medicinal. Iced teas tasted nice but did nothing.
So we made our own. The first batch was brewed in a French press, cut with mango juice, and shaken with a scoop of whey we ordered from a dairy co-op in Wisconsin. It wasn’t perfect, but it was the first one we’d finish without thinking about it.
Two years and a few hundred batches later, this is what we landed on. One flavor. Real ingredients. The label fits on the bottle because there’s not much to hide.
“We wanted a drink that earned its place on your desk without asking you to think about it.”
Reasonable
things to ask.
- Is there really only one flavor?
- For now, yes. Mango and orange were the first combination we couldn't stop drinking, so we shipped that one first. A second flavor is in testing for late 2026.
- What kind of protein is this?
- Cross-flow microfiltered whey protein isolate from grass-fed cows. No hydrolysates, no concentrates, no plant blends mixed in.
- Why does it need to be refrigerated?
- We pasteurize but don't sterilize. Keeping it cold preserves the brewed-tea aromatics and the natural fruit flavor — both of which die under heat.
- Where can I buy it?
- Through this site at launch, and a handful of independent grocers in the Bay Area. We'll expand from there once we get the cold-chain logistics right.
